Most large museums and art galleries today provide some kind of personal audio device that visitors can carry with them if they wish to learn more about the various exhibits on display. A similar idea has been implemented at the Brühl’s Terrace in Dresden, Germany, but instead of having to wear headphones or hold some device to their ear, visitors simply need to rest their elbows on a metal rail and cover their ears with their hands. Using bone conduction technology (or what they call ‘Touched Echo’) the sounds of airplanes and explosions simulating the air raid that occurred on February 13, 1945 are transmitted from the metal rail through the visitor’s arms and directly into the inner ear. The sounds are completely inaudible to someone who isn’t touching the rail, and since the terrace is located outside, the bone conduction system is a perfect solution because it’s completely weatherproof. I’ve also included a video that demonstrates how the system is used and what the simulated air raid sounds like.
